TEMPLET.

To all whom it may concern:

Be it known that I, HARRY B. As'i'i, a subject of the King of Great Britain, and a resident of the city of St. Louis and State of Missouri, in the United States of Amer ica, have invented certain new and useful Improvements in Teinplets, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

My invention relates to a teinplet, and has for its object the production of a templet structure including a very inexpensive pattern sheet.

My templet is more particularly intended for use in laying out locations for holes to be punched or drilled in structural beams.

The complete templet preferably includes a pattern sheet composed of cardboard or other light inexpensive material, and a pair of straight bars clamped onto the pattern sheet near one of its edges. The pattern sheet may have rough or irregular edges as the clamp barshave straight edges for alining the templet, and although the pattern sheet is composed of weak, flexible, and in expensive material, such as paper, it is amply reinforced by the clamp bars. These clamp bars may be used with an indefinite number of different pattern sheets to lay out locations for various different sets of holes. It will be noted that a teinplet so constructed may be used instead of the ordinary wooden and metal tcmplets, which must have one perfectly straight edge, and which can only be used to lay out a particular set of holes, for which the teinp'let is specially designed.

Figure I is a top or plan view of a templet embodying the features of my invention, showing it applied to a channel beam. Fig. II is an end view of the parts shown in Fig. I. Fig. III is a perspective view of. one of the templet members shown in Fig. I. Fig. IV is a detail view of one of the screw receiving members. F i V is a section taken on line VV, Fig. III. Fig. VI is a section taken on the line VI-VI, Fig. III. Fig. VII is a perspective view of a fragment of the pattern sheet.

In the accompanying drawings :A designates a channel beam having a web 1 and flanges 2. Pattern sheets 3 lying against the flanges of the channel beam are clamped between pairs of clamp bars 4: having Specification of Letters Patent.

straight edges, which lie on the web of the channel beam. The pattern sheets 3 are provided with suitable apertures for determining the position of holes to be drilled or punched in the flanges of the channel beam, and said pattern sheets are properly positioned when the straight clainp bars t are seated on the channel beam, as seen in Fig. II. To lay out locations for holes in the web of the channel beam, a perforated pattern sheet 5 may be interposed between the pairs of clamp bars 4, said pattern sheet having upturned edges (5 lying against the innermost clamp bars l.

In a teinplet structure built up as seen in Figs. I and II, it is necessary to secure the pattern sheet 5 to the bars and it is desirable to connect said parts by members extending across the channel beam. I therefore provide holders 7 having pivoted gripping fingers 8 and screws 9 for moving the fingers toward each other. The gripping fingers S are arranged in pairs so as to grip the clamp bars L and pattern sheet 5, as seen most clearly in Fig. II. Each holder 7 is provided with one or more apertures for the reception of a connecting bar 10, adjustably fitted to the holders. The connecting bars 10 may extend straight across the channel beam, or diagonally, but to produce an absolutely rigid connection, I deem it best to arrange these bars as seen in Fig. I. Set screws 11 are threaded into the holders 7 to secure the connecting bars thereto.

The pattern sheet 3 and clamp bars 4t may be used independently of the other parts of the teinplet structure shown in Figs. I and II, and I will now describe the novel details of construction associated with the clamp bars 4t and pattern sheet One of the clamp bars at is provided with screw receiving plates 12, and the other clamp bar 4L is provided with threaded screw receiving plates 13.

14: designates clamp screws passing through the plates 19. and having screw thread engagement with the plates 13. Each clainp screw 14 has a head 15, a neck 16, and an enlarged threaded portion 17. The neck 16 is surrounded by a collar 18 on the plate 12, said collar being split to allow the enlarged threaded portion of the screw to pass through the plate 12; and after the screw is properly positioned, the two sections of the split collar are forced toward each other, thereby interlocking the screw with one of the bars 4. The object of this interlocking feature is to positively separate the bars 4 when the screw 14 is turned to release the pattern sheet.

The pattern sheet 3 is provided with notches 3 for the reception of the screws 14, hence the pattern sheets may be applied to or removed from the clamp bars without removing the screws.

20 designates pins carried by one of the bars 4, and adapted to pierce the pattern sheet, as seen in Fig. VI, thereby positively holding said pattern sheet in the position to which it is adjusted.

As the templet is trued up with the work by one of the straight edges of a bar A, all of the edges of the pattern sheet may be rough and irregular; however, if the pattern sheet is to be removed from the holder for future use, one of its edges is preferably made straight, so-as to lie flush with the edges of the bars A. If this is done, the pattern sheet may be very easily positioned when it is again clamped between the bars A.

One of the bars A is preferably graduated, as seen in Fig. 111, to facilitate the work of locating the holes in the pattern sheet.

I claim 1. A templet, comprising two clamp bars parallel with each other, one of said bars being provided with a straight edge, clamp screws connecting said bars, the clamping screws being arranged in series longitudinally of said bars, and a pattern sheet clamped between said bars, said pattern sheet having a longitudinal straight edge lying flush with the straight edge on said bar.

2. A templet, comprising a pair of clamp bars, clamp screws connecting said bars, and a pattern sheet having one of its edges clamped between said bars, said pattern sheet being provided with notches extending to a margin of the sheet for the reception of said screws.

3. A templet, comprising a pair of clamp bars, clamp screws interlocked with one of said bars and threaded into the other bar, and a pattern sheet having one of its edges clamped between said bars, said pattern sheet being provided with notches extending to a margin of the sheet for the reception of said screws;

4. A templet comprising a pair of clamp bars, clamp screws having screw thread engagement with one of said bars and extending loosely through the second bar, each of said clamp screws having a head engaging the second bar, and a reduced unthreaded neck between said head and the threaded body, and a screw retaining collar in the second bar surrounding sald unthreaded neck, and a pattern sheet clamped between said bars.

5. A'templet comprising two clamp bars,

clamping means connecting said bars, a patv tern sheet adapted to be clamped between said bars and pattern sheet retaining pins carried by one of said bars adapted to be for forcing said fingers into engagement with said clamps, and connecting devices adjustably fitted to said holders. 7

8. A templet comprising two pairs of I clamp bars, a pattern sheet clamped between each pair of said clamp bars, a third pattern sheet interposed between said pairs of clamp bars, holders having pairs of pivoted gripping fingers adapted to grip the clamp bars and said third pattern sheet, and means for connecting said holders.
